Question

A number is drawn at random from the
numbers 1 to 50. Find the probability that it is divisible by 2 or 3 or 10.​

Answer 1

Answer:

Total outcomes = 50

Number divisible by 2 or 3 or 10 = 2,3,4,6,8,9,10,12,14,15,16,18,20,21,24,26,27,28,30,32,33,34,36,38,39,40,42,45,46,48,50.

No. of outcomes = 31

Probability = no. of outcomes/total outcomes = 31/50

Hope it helps..!!

Answer 2

Answer:

n(s)=50

n(no divisible by 2,3 and 10)2,3,4,6,8,9,10,12,14,15,16,18,20,21,22,24,26,27,28,30,32,33,34,36,38,39,40,42,44,45,46,48,50

P(E)=n(E)/n(s)

P(E)=33/50
